Speaking from experience i can comment there is a difference on road hazard warranty on OEM vs aftermarket of the same tire.
that likely has to do with the auto manufacturer...when you buy a new car, your tire's warranty is from the auto company, not the tire company...it is quite possible the auto company chooses less warranty for a price break.--
